Effects of social context on endocrine function and Zif268 expression in response to an acute stressor in adolescent and adult rats
… expression of Zif268 in neural regions after an acute stressor would be found in adolescent compared with adult rats. Samples were obtained before and after one hour of isolation stress and after either one or three hours of recovery back in the colony with either a familiar or unfamiliar cage …

Unravelling the role of tryptophan metabolism in the microbiota-gut-brain axis: focus on the effects of stress and exercise
… comorbid with psychological distress. The acute transitory reaction to an acute stressor and the associated adaptation over time, however, is not well understood. In this work, we investigated this neglected topic by evaluating the response to a psychological and a physical s stress …

Attentional Bias to Alcohol-related Cues in Social Drinking College Students
… may be found. The literature suggests that acute stress contributes to the development of problem drinking, especially among college students who utilize alcohol to cope with stress, and may serve as an environmental trigger for attentional biases toward alcohol and subsequent alcohol …

The effects of acute stress on retrieval of visual and spatial material
… dissertation was to explore the effects of an acute stressor (Study 1), and of administration of prednisone (Study 2), on retrieval of visual-spatial material (both emotional and neutral), and to compare the findings against three theories that attempt to account for the effects of stress on …

Exploring whether household pets buffer responses to a remote stress induction
… means of collecting physiological measures of an acute stress response. Research regarding stress reactivity often examines stress buffering, the phenomena wherein the experience of an acute stressor is dulled or recovery is assisted by environmental factors. Within the home environment, a …

Effects of Maternal Stress and Cortisol Treatment on Offspring Anxiety Behaviour and Stress Responses In Zebrafish (Danio rerio) and Largemouth Bass (Micropterus salmoides)
… exhibited an attenuated cortisol response to an acute stressor. Together, the results of the present thesis suggest that effects of maternal stress prior to spawn on offspring survival, growth, responses to stress, and anxiety-related behaviours are mediated, at least in part, by elevated …

Association between the magnitude of the immune response and recurrent major depression disorder in humans and depression-like behavior in animals
… response, possibly due to prior exposure to stressors. To investigate the validity of this hypothesis, a series of three complimentary cross-species studies was conducted. Study 1 examined the associations between circulating levels of inflammatory markers and <em>in vitro</em> immune …

Exteroceptive influences on total mood disturbance and perceived stress during green exercise
… of green exercise and the recovery after the stressor was explored. Results indicated that exercise with nature sounds, nature visual or exercise with both nature sounds and visual are better for recovery from an acute stressor than rest or exercise alone. Evidence provided in this thesis, …

The gut microbiota in depression
… self-reported stress, HPA axis response to an acute stressor, inflammation, cognition or neurophysiological measures. Taken together, these findings have furthered our understanding of the pathophysiology of depression. By incorporating the gut microbiota into existing neurobiological models of …

The Roles of Social Status, Maternal Stress, and Parental Investment in Modulation of Hypothalamic-Pituitary-Interrenal Axis Function in Teleost Fish
… levels, cortisol and glucose responses to an acute stressor were attenuated. Using an in vitro head kidney preparation, this attenuated cortisol response was attributed to lower ACTH-stimulated production of cortisol. By contrast, dominant status regulated genes associated with cortisol …

Stress Ecology of the Pacific Rattlesnakes (Crotalus oreganus and Crotalus helleri)
… hormone corticosterone (CORT) in reptiles. Stressors can have various impacts on vertebrate trait expression and may affect survival or reproduction. Little is known about the effects of chronically elevated CORT in free-ranging reptiles, or the effect of disturbance stress on venom …

Stress Reactivity Patterns in Breast Cancer Survivors and the Implications of Various Psychosocial Factors
… various environmental challenges, known as stressors. Numerous studies have observed impaired HPA response among White breast cancer survivors followed by an eventual normalization of the HPA axis, but little is known about SAM functioning, the complementary relationship between …

Autonomic and Behavioral Reactivity to an Acute Laboratory Stressor
… and coping in the context of a psychosocial stressor in a controlled laboratory setting. We examined the association between indicators of behavioral coping and underlying physiological reactivity within participants while experiencing stress. Participants included 68 emerging adults. …

The Behavioral and Physiological Effects of Long-Distance Translocation on Western Rattlesnakes (Crotalus oreganus)
… were assayed following the application of an acute stressor (the baseline blood draw plus one hour’s captivity in a plastic bucket). We also studied the effect of LDT on the CORT and T response (stressed concentration minus baseline concentration). Furthermore, we evaluated how LDT impacted a …
